化学气相沉积法碳包覆改性锂离子电池电极材料的研究进展

Surface-modification of Electrode Materials for Lithium-ion Battery by Coating Carbon Using Chemical Vapor Deposition Technique

主要介绍了CVD碳包覆工艺、包覆层种类和物理性质(结构、含量和分布)对电极材料电化学性能(首次容量、首次库仑效率、循环和倍率充放电性能等)的影响,在此基础上提出了尚需深入研究的问题,并对CVD法碳包覆改性电极材料的发展趋势和前景进行了讨论。

The influence of the CVD coating arts and coated carbon species as well as their physical properties （structure, weight percent, distribution and specific surface area ） on the electrochemical performances of the electrode materials （the first charge/discharge capacity, the first coulombic efficiency, cyclability and rate properties） are summarized, questions needed further studies are raised and the developing trend of modification is prospected.
